i40e: use xdp.frame_sz as XDP RxQ info frag_size
[ Upstream commit c69d22c6c46a1d792ba8af3d8d6356fdc0e6f538 ]
The only user of frag_size field in XDP RxQ info is
bpf_xdp_frags_increase_tail(). It clearly expects whole buffer size instead
of DMA write size. Different assumptions in i40e driver configuration lead
to negative tailroom.
Set frag_size to the same value as frame_sz in shared pages mode, use new
helper to set frag_size when AF_XDP ZC is active.
